This fall I made another version of this apparatus. The box I used was not big enough to cover the top of the table so I had to add an additional channel. To connect the extra channel, I duct taped it to the original and made a cutout so the corn could be pushed into the main section and down the ramp. I kept the end of the extra channel for strength and to create an additional obstacle for the children to work around as they moved the corn. I also made the ramp larger. Because of that, I could not use the usual tub at the end of the ramp because the sides were too high. I settled on an actual box.
The narrower channels, though, opened up new possibilities for play. The narrow channels became a platform above the channels on which to operate. And the children certainly took advantage of that.
I mentioned that the ramp was larger for this version of the channel apparatus. The corn and pellets have always made plenty of noise going down the ramp, but the large ramp amplifies the sound. Watch and listen!

The longer ramp also seemed to encourage more exploration from the bottom box. Of course, this box does not have very high sides, so it is easy to step into.
The child on the left is feeling the corn as another child is pouring it down the ramp. The child on the right has taken up residence in the box driving the dump truck up and down the ramp.
I have said before that this apparatus really encourages a specific type of spatial exploration. The flat horizontal channels encourage a straight, lateral motion. Watch how well that is illustrated by the clip below. The child "surfs" with his truck from one end of the channel to the other all the way to the bottom of the box.

When it comes to cardboard, there may be a general blueprint in my head for an apparatus, but I will rarely make the exact same apparatus a second time. That is partly because cardboard boxes are so varied in size and shape. If I were to search for boxes with exact dimensions from a previous version, I could spend too much time searching which takes away time for building. Besides, children are masters at exploring spaces. Children are masters at making the spaces their own. The more varied those spaces, the more play and exploration.
